ROCHESTER — The archaeologist who unearthed a Civil War veteran’s remains near Spaulding Turnpike Exit 15 last summer is giving a lecture at the Rochester Public Library in April.

Kathleen Wheeler, of Independent Archaeological Consulting, LLC, will discuss exhuming the remains from the Legro/Leighton Cemetery near the Exit 15 ramp on April 22 at 7 p.m., according to Dan Meehan of the Sons of Union Veterans of the Civil War. The removal was conducted as part of the N.H. Department of Transportation’s expansion of the Spaulding Turnpike.
